Compound of Carbon and Hydrogen 92 3
On the analysis of a hydrocarbon
There is a hydrocarbon in which the content of carbon is 92.3%. From this, it can be seen that the ratio of carbon to hydrogen in this compound must have its specific laws.
The atomic weight of carbon is about twelve, and the atomic weight of hydrogen is about one. Let the chemical formula of this compound be\ (C_xH_y\), and according to the carbon content of 92.3%, there is\ (\ frac {12x} {12x + y} = 0.923\).
After calculation and derivation, the relationship between\ (y\) and\ (x\) can be obtained. From the above formula\ (12x = 0.923\ times (12x + y) \), that is,\ (12x = 11.076x + 0.923y\), the shift term can be obtained\ (12x - 11.076x = 0.923y\),\ (0.924x = 0.923y\), so\ (y\ approx x\).
From this, it can be preliminarily speculated that the simplest formula of this compound is\ (CH\). There are many common hydrocarbon-containing compounds, but those with this ratio relationship, such as acetylene\ (C_2H_2\), are consistent with this ratio. Taking acetylene as an example, its carbon content is\ (\ frac {12\ times2} {12\ times2 + 1\ times2} =\ frac {24} {26}\ approx0.923\).
From the carbon content of hydrocarbons, the approximate chemical formula can be deduced, which is of great significance for the study of the properties, structures and uses of such compounds. According to its chemical formula, its chemical properties, such as flammability and addition reactions, can also provide theoretical basis for chemical production, material preparation and other fields.
